vention, sue-h as will enable others skilled in the art to which it anpertains to malte and use the same.

This invention relates to valve strurlures for gas engines and has for an ohiei'i to geoerallyiniprove the particular valve structure described in my tto-pending application Yfor Letters Patent5 filed l'v'lareh 14.', lill, under Ser, No. (3837737.

An object of the or sont; inventimi to provide the valve with internal webs to preient warping of the valve out of shane, and furthermore to provide the valve with piston rings which prevent leakage past the valve and facilitate rotation of' the valve, there beine; novel hall hearings assembled with the valve to promote the easy and free rotation of the valve.

With il i above, objects in view the invention consists of certain novel details olf eon strurtioir and combination of Darts .hereinafter fully described and rlaiineth it heingr understood that various modifications may he made in the nlinor details of construction within the scope ot the appended elaini.

ln the accompanyiner drawings 'forming part of this specification :'liig'ure l is :i side elevation of a single 'eylinder engine with iuy hoort-)ved valve amiiied thereto, the valve heilig' shown in seriion. l `i;r. 2 is a longitudinal section on the line 2u-H2 Fin'. l. Fig'. is a sectional View through the '.'a ive whaniher with the valve removed. hin'. l is o the steel hearing rines.

Referring' now to the ldrawings in nhi'h like Characters of reference designate siinilar parts, l0 desinnatesa ras engine eyiinder within which works a piston l1 having" a piston rod- 12 which is (meratsvely oonneoted to a crank shaft i3 that is 4iournided in the oi ank case 14.

'-lhe cylinder head 'l5 is provided on one side with a Cylindrical valve chamber lil whieh is water-jacketeifl as shown at .i8 and comm nieates with the clearance space i7 the cylinder through .spaced 'inlet and exlllin. 5 is ar 20 resiieetively. The cuisine is closed by a or 1e with an upwardly direeted flange Yf d the ton of the Valve easing` is closed by ping havingr a downwardly directed l 'l'he valve orly 25 ttirefisely within the valve cas :fr its ripper and lower ends 'raged the plug and or the 'valve easing with the plug tlanfge Q45; and bottoni flange 22 retaining the valve in position as shown in Fig. l. The valve body is provided with a central cross par ion 3G to which a stand shaft 27 is fixed for roiaiing the valve, the lower end ige 24.

of this shaft heine; connected by a train of 'gearingg io the crank shaft. This 'train oi nearing if; so proportioned that the valve 'i 1ll he turned tii''onggh one complete revolution for every two revoiiitions of the crank shaft. is in nay eoepending application the valve is 'provided above the partition wall with a port 29 adapted to register with the intake port of the cylinder during the intake stroke. of the iiistrmry and below the partition with a pori; 5G adapted to register with the outiei' port oi the cylinder during 'the exhaust si relie: n intake pipe 3l is connected io he nlug, and an outlet pipe 32 is connected to the iioltoxn oli the valve easing.

The parts above described are constructed in accordance with iny foriner` invention, the present invention heine; in the nature of iniproveinenison the valve body Arranged above and below the partition wall 2li are webs 33 which strengthen the, Cylindrical wall of the body against warping, these wells helingr of skeleton structure as shown to facilitate passage of the fresh and learn gases tlierethroinrh. A plurality of piston rings' fifi are inonntedin i-:iroulnferential ,grooves Yformed inv the cylindrical body and prevent leakage oi? the rases pest the hotly. honored in the upper and lower external of the body are cone surfaces 35 within which are conlined balls 36, these `halls ridin f n )on bearinv rin s of the env s H eral shane shown at 37; which rings are interposed between. the valve chamber and the valve body as clearly shown in Fig'. l. Duripa'tented Ania l5, 191 3.

comprises a hollow Cylindrical ingr rotation of the valve these halls promote the free and easy turning of" the valve. What is claimed, is :-A The combination' with a gas engine of a valve einander hin/ing an npstanding flange rings confined in the spacesbetvveen saidcone surfaces and said plug and valve bottom respectively, and balls confined. between and bearing upon said rings and cone surfaces.

In testimony whereof, I aHX my sigmture, in the presence of two Witnesses.
